摘要：

The energy spectra of heavy quark bound states are analyzed using the error-function-type potential and the one-gluon-exchange Coulomb-type force. The Debye screening mass at finite temperature and density is studied in the thermofield dynamics approach The critical temperature and critical energy density for J/psi dissociation in hot and dense matter are obtained.
